imap Apple Mail account Using too much room on disk
Can anyone explain why the gmail server says I'm using 4.22gb of server space, but my computer that has this email account imap-ed is using about 360gb?
I'm using a El Capitan on a mid 2014 15" Macbook Pro.
(I need El Capitan for business reasons)
Is there a way to delete superfluous data without losing the messages?
Would it clean anything if I deleted the email account from my Apple Mail, and then re-imap-ed it?
I'm running out of space on my disk.
MacBook Pro 15″, OS X 10.11
